Specification of Letters Patent.

Patented April 24, 1906.

To ffy/ mii/ont it 7am/y cancel/n.-

Be it known that I, HENRY CHRISTIAN GEORGE KREUTZKAMP, a citizen of the United States, and aresident of the city of New York, borough of Nlanhattan, in the county and State oi N ew York, have invented a new and Improved Oven, of which the following is a full, clear, and exact description` This invention relates to ovens such as used for baking food.

The object ofthe invention is to produce an oven which is specially adapted to be used in connection with a gas-stove, further objects of the invention being to provide improved means for regulating the distribution of the heat within the oven and preventing radiation of heat therefrom.

The invention consists in the construction and combination of parts to be described more fully hereinafter and definitely set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of the oven. Eig. 2 is a cross-section of the oven, taken from front to rear thereof. Eig. 3 is a transverse section taken substantially upon the line 3 3 of Fig. 2, and Eig. 4 is a horizontal section taken upon the line et 4 of Eig. 2.

VReferring more particularly to the parts, 1 represents the body of the oven, which is of rectangular or box form, as indicated, said body being completely enveloped in a acket 2. This body and jacket are preferably constructed of sheet metal, and the body is of reduced dimensions with respect to the jacket, so as to Vform a double wall for the oven, in the interior of which a packing 3 of asbestos or similar material is received. The bottom 4 of the oven is formed oif a single sheet of material and is preferably formed with a centrally-disposed opening 5, in which there is mounted a removable sleeve 6, which normally projects downwardly below the bottom, as indicated in Eig. 3. The upper edge of this sleeve is formed with an outwardlyprojecting lip 7 which is adapted to support the sleeve upon the bottom.

I provide a cover' S for the oven having a double wall filled with asbestos 9, as shown,

y The outer wall of this cover constitutes a part of the jacket, and the inner wall is to be considered a part of the body.

As indicated in E ig. 4, the asbestos packing 3 for the vertical walls of the oven'is formed in a single sheet, the forward edges 1() of the side walls of the acket being turned inwardly, so as to clamp the opposite edges ol' the sheet7 as will be readily understood. In this way lips 1l are formed at each side. Referring again to Fig. 4, the forward wall 12 of the body is formed with a large opening or doorway 13, at which there is attached a main door 14, the same being mounted upon a hinge connection 15 at one of the vertical edges, as indicated most clearly in Fig. 1. This door is formed with an opening 16 and is provided on its rear side with a rectangular cleat 17, which operates to retain a pane of glass 1S or similar transparent material. The edges of this glass 18 abut against an asbestos washer 19, which insulates the glass largely from the heat of the oven-body.

The body1 is inserted in the jacket by forcing the same inwardly toward the rear wall, so that the body passes inwardly between the lips 11, referred to above. The bottom 4 and the outer sheet of the cover 9 are formed at their edges with beads 20, against which the edges of the vertical walls rest, as indicated most clearly in Eig. 3.

The body is retained within the jacket by vertical bolts 21, preferably four in number, as indicated. These bolts have heads 22, which lie against the under side of the bottom 4, and their upper extremities project beyond the cover 9, so as to receive nuts 23. Upon the projecting extremities of these bolts handles 24 are applied, the same having openings in their feet 25, through which the bolts pass. The bodies of these handles are offset, as indicated in Eig. 2, so as to form grips 26 for thc fingers, enabling the oven to be readily moved from place to place. Around the bodies of the bolts 21 sleeves 27 are placed, preferably three in number, as shown, and between the adjacent edges of these sleeves collars 2S are provided. These collars are preferably of circular form, as indicated in Fig. 4, and provided with central openings, enabling them to be slipped over the bolts, as will be readily understood. These sleeves, together with IOO the collars, substantially fill the space between the bottom and the cover, so that when the nuts 23 are tightened up, the parts are all firmly held in a fixed relation.

The collars 28 aord means for supporting shelves or gratings 29 and 30. The grating 29 consists simply of a plurality of crossed bars 31, the outer members of which, 32, extend in a front and rear direction, and rest upon the inner portions of the collars, as shown most clearly in Fig. 3. Adjacent to the collars the transverse bars 33 are formed with downwardly-projecting spurs 34, which I are disposed on opposite sides of the collars and prevent the grating from becoming displaced accidentally.

The body of the grating 30 is similar to the grating 29 just described, being formed of crossed slats or bars 35. This grating is provided with a downwardly-projecting stud or post 36, as .indicated in Fig. 2, and this stud affords means for attaching a deiector or cover 37. This deiiector is of rectangular form, as indicated in Fig. 4, and is preferably formed of four triangular plates 38, which are connected at their center or apex 39, so as to form a hood. This grating 30 is inserted from the front of the oven in the same manner as the grating 29, being slid between the bolts 21, as will be readily understood.

In using the oven it will be placed upon a gas-stove, so that the gas-burner will lie substantially in or beneath the sleeve 6. The defiector or hood 37 then aords means for distributing the heat within the oven, being capable of assuming two positions, as indicated, respectively, in Figs. 2 and 3. In this connection it should be understood that the entire grating is turned over bodily, so that the hood may be disposed either below or above the same. I/Vhen arranged as in Fig. 2, the heated gases which arise through the sleeve will be deiiected outwardly toward the side walls of the oven, and a large proportion of the heat will thus pass upwardly toward the upper shelf 29. When it is desired to retain the heat at the lower shelf 30, the arrangement shown in Fig. 3 would be adopted, in which the hood is in a reversed position. In this way the heated gases arising through the sleeve 6 are caught and concentrated by the hood. In this way a high temperature results just below the hood, enabling food to be cooked upon a frying-pan or' griddle held at this point.

Below the main door 14 a narrow auxiliary door 40 is provided, and these doors may be opened independently and independently locked by knobs or latches 41.

The sleeve 6 does not operate to prevent the oven from being set upright upon a level support, for the reason that this sleeve is loose and becomes displaced upwardly into the interior of the oven, as indicated in Fig. 2, the lower edge of the sleeve being engaged by the support, which operates to displace the sleeve, as will be readily understood.

In roasting food in the oven the food is placed in a pan which rests on either of the gratings.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. -An oven adapted to be applied to a gas-stove and having an opening in the bottom thereof, a loose sleeve normally hanging in said opening and adapted to pass u wardly into the interior of said oven to al ow the same to rest upon a horizontal surface.

2. In an oven in combination, a body, a plurality of bolts passing upwardly therethrough, collars carried by said bolts and projecting laterally therefrom, and removable shelves supported on said collars.

3. In an oven in combination, a body, a plurality of bolts extending upwardly therethrough, a plurality of sleeves carried by said bolts, collars carried by said bolts between said sleeves, and shelves supported on said collars.

4. An oven having a body, a jacket surrounding the same, asbestos packing between said jacket and said body, a plurality of bolts passing upwardly through said body and attaching same to said jacket, said bolts having projecting extremities lying above said oven, and handles attached to said extremities.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HENRY CHRISTIAN GEORGE KREUTZKAMP.
